test cases that loads images via new Image

This test case loads 50 512x512 images via new Image().src = "data:...".  This causes a memory growth of ~400MB.

Since the image is 512x512x4 bytes/pixel, the data URL size is 512*512*4 * 4/3 (base64) * 2 (utf-16 encoding) = 2666kb/image.  Given 50 loads this should be a memory use of 133MB, which means that we are leaking 3 copies of the URL per load.  I imagine that we're doing deep string copies in a few places that perhaps we don't mean to, in addition to leaking it.
